What are the functions of the Greater and Lesser trochanters of the femur?
Specifically, the greater trochanter is larger and serves as an attachment to muscles including the gluteus medius and minimus, piriformis, obturator internus and externus, and gemelli muscles. The lesser trochanter serves as an attachment to muscles such as the psoas major and iliacus muscles.
Where is the lesser trochanter?
femur
The lesser trochanter is a small protuberance of bone that projects from the posterior aspect of the femur, inferomedially at the base of the femoral neck.
What muscle attaches at the lesser trochanter?
psoas major muscle
psoas major: The psoas major muscle arises from the bodies of the second to sixth lumbar vertebrae. The muscle is inserted into the lesser trochanter of the femur.
What is lesser trochanter femur?
The lesser trochanter is a pyramidal process that projects medially from the shaft of the femur and receives insertion of the iliopsoas muscle. Isolated fracture or detachment of the lesser trochanter is an infrequent occurrence and is most commonly seen secondary to avulsion in adolescent athletes.
What is the function of the greater trochanter?
The position of the greater trochanter influences the mechanical stress of the hip joint, the extent of contraction of the gluteus medius and minimus muscles, and the mechanical stress of the femoral neck.
What is the purpose of the trochanter?
A trochanter is a tubercle of the femur near its joint with the hip bone. In humans and most mammals, the trochanters serve as important muscle attachment sites.
Is the lesser trochanter part of the hip joint?
Trochanter: This is part of the upper femur. There is a large outer bony prominence called the Greater Trochanter and a smaller one inside the groin called the Lesser Trochanter. The part that you can feel as the outermost bit of the hip that you lie on is the Greater Trochanter.
Is the lesser trochanter palpable?
The ischial tuberosity lies on the same transverse plane as the lesser trochanter, which is not palpable and arises from the posterior medial surface of the proximal femur.
How do you palpate lesser trochanter?
The lesser trochanter attachment of the femoral belly can sometimes be successfully palpated with the client in side-lying position. To palpate the right-side femoral belly, the client lies on their right side with the right thigh in partial flexion at the hip joint and the right leg flexed at the knee joint.
What is the purpose of a trochanter?
Where are the greater and lesser trochanter projections located?
The greater trochanter can be felt just under the skin on the lateral side of your upper thigh. The lesser trochanter is a small, bony prominence that lies on the medial aspect of the femur, just below the neck.
What is greater trochanter of the hip?
The greater trochanter is located at the top of the thighbone (femur) and is the most prominent and widest part of the hip.

Abductor Dysfunction
The greater trochanter is the attachment site for five muscles: the gluteus medius, gluteus minimus, piriformis, obturator externus, and obturator internus.
